I remember reading somewhere about a non-scientific experiment concerning riding gear.
First the guy rode with very high visibility gear.... reflective vest ...bright helmet etc and kept track of the number of infractions against him by cages.
Next he rode in "biker gear" black leather black helmet etc.and kept track.
Third he rode dressed looking like a motorcycle cop.
The infractions for biker gear and reflective gear were about the same. Only when he dressed as a cop did the number of infractions drop significantly.
The point was not so much that cages don't see motorcycles as they don't SEE them as a THREAT. I have noticed this myself. I have people look right at me and pull out in front of me when I'm on the bike. I drive a sidecar with lights on both sides and it seems hard to miss.
I also drive a very small Red Toyota Yaris and people are always cutting me off, but when I drive my 4x4 Diesel truck with a plow on the front, I hardly ever get cut off.
Is it because they see my truck better than a red car or just that they see it as a threat with a big Gnarley Plow on front?
